‘Huangying 1’ cherry tomato variety was used as the experiment material，the soil treatments considered were,conventional biological organic fertilizer applied as control(CK)，based on the basal，adding humic acid as T1，adding humic acid plus bean cake as T2，adding humic acid，bean cake and soybean powder as T3，adding humic acid，bean cake，soybean powder，and stevia sugar as T4.The experiment was aimed to study the effects of different material ratios on the fruit quality，soil nutrients，and soil enzyme activities，to select the optimal organic materials composition.The results showed that comparing CK，T1 and T3 significantly increased the relative growth rate of plant height.Plant height，stem diameter，chlorophyll content，and leaf number were all lower in T2 and T4 significantly.T3 and T4 significantly increased the content of soluble solids and the ratio of sugar to acid.Adding organic materials all could improve the solution，sugar-acid ratio than CK.On the contrast CK，T1，T2，and T3 all increased soil EC，adding organic materials did not change the soil total nitrogen，carbon-nitrogen ration，soil available P was increased by 22.36% and 19.61% in T1 and T3 respectively，soil available nitrogen was higher 57.98%，while soil sucrose activities accelerated with T1 and T4，T2 soil phosphatase activity promoted.Based on the principal component analysis showed that overall scores was T3>T1>T4>CK>T2，the ratio of basal，humic acid and bean cake was 5∶2∶5，meanwhile soybean powder was 5 kg?m-3 was the best treatment for high-quality cherry tomato production.
